5 Claims, 4 Drawing Figures SWIM TRAINING PADDLE BACKGROUND OF THE INVENTION It is well known that there is a point of maximum efficiency of hand movement through water for a swimmer. This maximum efficiency depends upon the speed, angle and pitch of the hand as it moves through the water. Actually it has been discovered that the maximum efficiency depends upon variation of the speed, angle and pitch as the hand moves through the water. This variation requires that the hand oscillate to different positions as it moves through the water. It has been discovered that a paddle assists the swimmer to be able to perceive this variation.

The use of swimming paddles in itself is old. However, the swimming paddles of the prior art are known to have certain disadvantages. It is common for previous paddles to place a strap entirelyabout the fingers of a swimmer. The paddle of the present invention, as will become apparent further on, uses a band or strap about a single finger which creates a narrow fulcrum. A broad fulcrum is basically insensitive in comparison to a narrow fulcrum. It is agreed that the manipulation of a paddle is harder to control with a narrower fulcrum. But the narrower fulcrum accentuates the swimmers sensitivity to the position of the hand at the most efficient position.

Another common problem of paddles of the prior art is that they restrict movement of the wrist. The aft end of the paddles of the prior art tend to bite into the joint adjacent the wrist which restricts the joint movement and bites into the skin. The paddle of this invention has overcome this difficulty by being relieved at the aft end of the paddle,thereby eliminating the possibility of the paddle biting into the wrist.

Another problem of paddles of the prior art is that they encounter difficultyin recovery at the end of the stroke. In other words,if the water force acts against the forward propulsive movement of the swimmer at the end of the pull phase of the stroke, this tends to slow the swimmer and decrease the swimming speed. This resistance in recovery is normally caused by the water being conducted between the hand and the paddle. I

The paddle, of this invention holds the swimmers han'd firmly to the paddle at all times and does not permit water to enter between the paddle and the hand. Therefore, the resistance to the recovery movement and forward progress is minimized.

Previous paddles have normally been constructed of a material which does not float. With a swimmer swimming in dark areas, in dark murky'water or ocean water and the paddle is lost, it is not uncommon for the paddle to never be found. Also, if the paddle was located at the bottom of adeep pool, it may be unsafe toretrieve the paddle.

In aneffort to avoid this, the paddle of this invention is constructed of polyethylene plastic which floats and can be readily colored to assist in finding a lost paddle. Frequently, the paddles of the prior art were constructed of a material which could not be colored other than painted which inevitably became chipped.

Another main disadvantage of the paddles of the prior art is that the paddles did not incorporate any relieved area which caused such to cut the wrist. It has been discovered that the inherent repetitive movement of the swimmer during use may cause an unrelieved paddle to cut the skin and blood vessels of the wrist.

Also the sharp edges of previous paddles frequently cut clothing, including swimming suits. The paddle of this invention has no sharp edges which can cause damage 5 .or injury.

It is common for the previous paddles to be constructed in only one size. This size paddle may not be the optimum size paddle for a particular size hand of an individual and that person cannot achieve maximum efficiency of movement through the water. The paddle of this invention can be readily constructed in numerous sizes so that a particular swimmer can select the particular size of paddle which is most suitedto his sized person.

Another disadvantage of the paddles of the prior art is that the bands which retain the hand of the paddle are normally integrated with the paddle. Therefore, if the band broke, the entire paddle would be discarded. An advantage of the apparatus of this invention is that the bands of this invention are a readily commercially available item and if they break can be readily replaced. Therefore it is not required to discard the paddle.

25 BRIEF DESCRIPTION OF THE DRAWING DETAILED DESCRIPTION OF THE SHOWN EMBODIMENT Referring'pa'rticula rly to the drawings, there is generally'shown in FIG. 1 the paddle l0 of this invention being composed of a sheet material base 12 with the aft end of the base 12 having a relieved area 14. The base 12 isto be manufactured from polyethylene plastic so as to float upon water. The swimmer is to insert'his hand 16 against the base l2 as is shown in'FIG. l. The relieved area 14 is located directly adjacent the wrist of the swimmer and is to substantially unhinder thepivoting of the hand with respect to the wrist,

Located within the base 12 is a first pair of openings 28 and 30 located adjacent the aft end'ofthe base 12. Also located in thebase 12 is a second pair of openings 20 and 22 located intermediate the ends of the base 12 but nearer the fore end of the base 12. Bands' 24 and 26 are to be employed which will normally take the form of lengths of flexiblerubbertubing. This tubing is to be soft readily flexible rubber and can be easily stretched. A common form of such tubing is frequently termed surgical tubing. 1

Each end of the band 24 is to be stretched and inserted through the openings 20 and 22 such as is shown in FIG. 4 of the drawings. Also in a similar manner the ends of the tubing 26 are to be stretched through openings 28 and 30. The amount of the tubing that can be inserted through the irrespective openings can be readily varied so that adjustment of the bands 24 and 26 may be readily accomplished. This is desirable so that the paddle of this invention can be readily adapted to fit the hand of eitheran adult or a child.

This adjustment is readily shown in broken lines in FIGS. 3 and 4 of the drawings.

It is to be noted that the band 24 is adapted to extend around only the middle finger 18 of the persons hand. This is particularly desirable so as to provide a substantially narrow fulcrum for the hand of the swimmer which causes that person to be extremely sensitive to movements of the paddle 10. This sensitivity is readily desired so that whenever the paddle assumes an inefficient position when being conducted through the I water, the swimmer can make adjustments in the position of the paddle to make the movement through the water more efficient.

I claim:

1. A swim training paddle comprising:

a base composed of a rigid sheet material, said base having a fore end and an aft end, said aft end of said base being relieved, a first pair of apertures formed within said base adjacent said aft end;

a first flexible tubing to be conducted through said first pair of apertures forming a loop to be located about a swimmers wrist; and

a second flexible tubing to be conducted through said second pair of apertures forming a single loop to be located solely about the middle finger of the swimmers hand, whereby the swimmers hand is fixedly positioned upon the paddle with the pivotal movement of the hand about the wrist being substantially unhindered due to the relieving of said base, and whereby the most efficient position of the paddle as it moves through the water is most sensitive to the swimmer due to the narrow fulcrum about the middle finger.
